Preventive Maintenance
In order to keep your tank cleaning machine servicing you as an efficient tool in your tank cleaning
operations, it is essential to maintain its high performance by following a simple preventive maintenance
programme.
Good maintenance is careful and regular attention!
The following recommended preventive maintenance is based on tank cleaning machines working in
average conditions. However, you will appreciate that a tank cleaning machine, which has a rough and dirty
job to do, will need more frequent attention than one working in ideal conditions. We trust that you will adjust
your maintenance programme to suit.
Recommended Preventive Maintenance
Every 300 work hours disassemble the machine according to the instruction "Dismantling and Assembling"
(page 14-19).
Clean material build-up and deposits from the internal parts. Inspect and clean the individual parts with
Scotch-brite, S-Ultrafine, or chemical cleaner. Do not wipe with cotton waste, use always a non-fluffing cloth.
Special attention must be directed to the wear parts. To check which parts that are wear parts, please see
Reference Lists of Parts, page 23-24. Replace worn or damaged parts.
When holding components in a vice, use lead or aluminium jaws or jaws made from other soft material. If it is
necessary to knock any components, use a plastic hammer.
Never place parts directly on dirty floors or tables. Always place the parts on a piece of cloth, cardboard, etc.
Always perform all assembly/disassembly steps in the order described in this manual. Never assemble
components without previous cleaning. Work in a well-lighted work area.
Note
: Recommended tightening torque for all screws: 4-5 Nm.
